Hi guys, come Tuesday morning i am going to ring around the specialists ( api,scooby clinic etc) for prices and a guide for getting my sti v4 engine rebuilt but I would like to go into the conversation with a bit of knowledge on what I want/will be asking for.
My sti has done 83k runs sweet at the minute but I am thinking of getting her rebuilt very soon so I will a) have the piece of mind it will last a long time and b) I can get more power out of her. I want 350bhp for now but would like the option of having an engine capable of 400bhp in the future when I have the money for a bigger turbo,injectors , gearbox etc but 350bhp for now but I must emphasise I want a solid reliable engine that can easily cope with 350bhp than a fragile one that can do 450hp .
I am hearing a lot on a 2.1 strokes or a semi closed 2.0 but I really don't know where to start and what the difference is, I know I want forged for strength , what is one stage of from a standard sti v4 spec and will that be sufficient ?

Cheers boyos

just bought one to replace mine, 148,000 miler, after it blew a hole in a piston and emptied its oil out of the dipstick hole. I am looking at getting a new crank rods and rebore with forged pistons gas flowing it etc , just wondering if its worth having a stroker kit,If anyone has had this done , is it worth it?

might be worth considering a newage engine?

I have a sti8 short motor 83 k mint condition 700

These handle over 400 all day long and don't break the bank

What is your end goal with the car? The best thing to do is to just ring someone like David at API and explain to him what you're wanting from the car now and in the future. He will give you your options and tell you what is best to start from and won't try to sell/build you something you don't need.

Hi there

As above New age STi engine will be cheapest route and which will last 400bhp+ if you are looking for 400bhp+

If you are looking to run more power and want to have forged build,I would go over 2.0L with 2.1L which will be best option

Newage Sti motor would get my vote at that level of tune, I'm at 450hp with mine and may be pushing for more shortly, good hardy motors they are if looked after well

Scubadog86

My end goal is to get a strong engine that can handle 350bhp all day long without a sweat, and if I want to push it up then I can at some stage,but my main goal is to not have the worry of pushing my car on the current engine and having it go bang , piece of mind really, second hand engines are cheaper but how we're they treated in their previous life?

forged 2.5, at 350 will ne nigh on 400ftlb and then if you want more later will easily go 400+

Scubadog86

Any ideas on the price on those beasty forged 2.5 I heard they r big bucks

Tidgy

Not sure on exact going rate on them in truth, but for roads use it prob the best engine due to the low down grunt they produce. Worth looking into though

I agree with Tidg, I went for a ride in a fully forged 2.5 classic not so long back and the way it pulled was awesome, although he did have twin avcs on it, but the lowdown grunt was v good considering he is running a gt35 iirc which is a big turbo as we know, and that got up an went without breaking a sweat

I would seriously consider a forged 2.5 with my twinscroll setup, I think it would make for an awesome road car its just the cost of it, when you can get a tried and tested 2.1 built for less money and will stand up to a good hammering, unless I had the block fully reworked on the 2.5 and pinned etc then I would probably still have a doubt in my head that it would let go, I know its probably unlikely but its still more likely to go wrong under intense loads than a 2.1 IMO from what I have personally found from research and speaking to a few people about them, now if I could have the same spec engine as Mr Rawle then I would be all over it like a rat up a drain pipe but I would imagine the costs to be quite high

Hi Scubadog..

Your inbox is full! give it a flush out and I'll send you a PM...

Semi closed deck 2.1, nitrided crank, steel rods, Mahle pistons,11mm oil pump, acl race series bearings, assembled ready to bolt your heads on £2.5k from me.

Tidgy

let the bidding war begin lol

Scubadog86

Is that price fitted, skimmed and ported polished heads, in no way shape or form do i know what I am talking about lol I'm just putting bits and bobs from other conversations together as I have been told to get the heads ported and polished ha ha ha but that is a good price , providing a 2.1 semi closed deck is good and can handle the power, like I said mechanics especially engine rebuilds are over my head.

Scubadog86

Newage Sti motors are between 1500-2000 for low mileage, what kind of work is required to fit that in a classic if I went down that route if I can't get what I want

Not a great deal, it would be the same amount of work putting a standard engine back in

You just build the engine up on the deck ( put heads on, manifolds, etc )or get who ever you want to use to assemble it, then simply drop it back in and away you go

wms-racing

My price is for the supply of the short engine only, inc delivery and vat. I can swap your parts over onto the short engine, price can vary a bit depending on headstuds used, gaskets, heads re-built, new cam belt/kit water pump etc. Ball park figures would be parts swapped using steel headgaskets and std head bolts £3000, the same but with an arp headstud kit, new water pump and cam bet kit £3400. All these are if the engine was taken out for me + £500 to remove and re-fit inc oil etc.
If your not sure about headstuds and gasket options a rule of thumb is up to 400bhp std head bolts are ok, 400-500bhp arp 11mm headstuds, over 500bhp, closed deck with 14mm

Hi mate, I'm looking in to a similar thing on v3 sti
I'm thinking of getting a new age short motor at about 6-700 quid, then I'm going to get my v3 heads rebuilt and bolt them to the top of the new age block with arp studs and new gaskets, don't know cost of head rebuild? New water pump, new Cam belt, new clutch and it should make for a worry free engine good for 400 bhp
I suppose I'm looking at 2k tops, bit of a remap and it should be over 300 hp with no dramas. Either that or double my budget for a good rebuild!
There's a lot of parts that you may as well replace while its all out and then it gets expensive

Tidgy

be a bit weary what you buy, some second hand engines can let go very soon after you fit them and you will struggle to get any sort of warrenty on them, very easy for them to wriggle out of any failures leaving you out of pocket and back to same situation. also be weary of 'reconned' sometimes they can be jetwashed and sold as reconned.

best bet get a rebuild done by a reputable tuner.

RUDDY

I know tidgy, that is indeed the only major concern with this route! I'm having these thoughts all the time lol! It would be soul destroying to do all of that only to start it and bottom end is knocking on the plus side there must be some great short motors out there with not many miles on! Certainly a tough decision.

Tidgy

I think its a budget thing tbh, if you can stretch to getting a proper rebuild then theres no other way to do it.

Untill its stripped down you wont know the damage though

Scubadog86

Wow so much to think about hear. Open block or a semi closed block ? Decisions decisions. I only want max 400bhp but then you never know in future, I mean if I spend this money on a engine I an on having her for a very long time I just want reliability first and formost

wms-racing

An open deck is fine to 500bhp with decent headgaskets and an arp stud kit, that would save you £300 off my quote.
A few Peope have said to be wary of a used short engine, wise words. Ive just done 2 hatch STI rebuilds, both had broken pistons, both 2008, one with 28K, one with 34K, the owners wanted them fully rebuilt with new bearings etc. One had a few bearings worn through to the copper, the other had all bearings worn through, both cars ware standard with FSH.
Pay cheap.....pay twice!
